METHODS: 39 depressive patients, 22 manic patients and 33 normal controls were included in the study. Visual, auditory and somatosensory evoked potentials (VEP, AEP & SSEP) were recorded from every subject using a Nicolet Spirit Instrument. RESULTS: Both the depressive and manic groups presented prolonged latencies and decreased amplitudes of major components of SEPs as compared to that of normal controls. Depressive patients with suicidal behavior had decreased P(3) amplitude of VEP (P展开更多
